Adapter configurations 123
4—Advertise both Rx and TX flow control being enable and negotiate with link partner. If link
AutoNegotiate is not enabled, then both Tx & Rx Flow Control are disabled.
Example: FlowControl=0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0;
• MaxJumboFrameSize. Configures the Jumbo Frame feature of a link. The valid range for this
parameter is 0 to 9000. If the value configured is less than 1500, then the Jumbo Frame feature is
disabled. BCM5705 adapters do not support jumbo frame and this parameter will be ignored by the
driver
Example: MaxJumboFrameSize=0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0;
• TxPacketDescCnt. Configures the number of Tx packet descriptors. The valid range is 32 to 512.
More system memory resources are used for larger number of Tx Packet Descriptors. The default
value is 200.
Example: TxPacketDescCnt=200;
• RxStdDescCnt. Configures the number of Rx packet descriptors. The valid range for this parameter is
32 to 512. More system memory resources are used for larger number of Rx Packet Descriptors. The
default value is 500.
Example: RxStdDescCnt=500;
• RxJumboDescCnt. Configures the number of Rx Jumbo packet descriptors. The valid value is 32 to
256. More system memory resources are used for larger number of Rx Jumbo packet descriptors.
This parameter is only used if the jumbo frame feature is enabled. The default value is 50.
Example: RxJumboDescCnt=50;
• RxCoalescingTicks. Configures the number of Rx Host Coalescing Ticks in microseconds. This
determines the upper-boundary of the time interval that the device will generate interrupts if one or
more frames are received. The default value is 150.
Example: RxCoalescingTicks=150;
• RxMaxCoalescedFrames. Configures the number of Rx Maximum Coalesced Frames parameters. This
determines the upper-boundary of maximum number of Rx buffer descriptors that the device
processes before it will generate an interrupt. The default value is 10.
Example: RxMaxCoalescedFrames=10;
• TxCoalescingTicks. Configures the number of Tx Host Coalescing Ticks in microseconds. This
determines the upper-boundary of the time interval that the device will generate interrupts if one or
more frames are sent. The default value is 500.
Example: TxCoalescingTicks=500;
• TxMaxCoalescedFrames. Configures the number of Tx Maximum Coalesced Frames parameters. This
determines the upper-boundary of maximum number of Tx buffer descriptors that the device
processes before it will generate an interrupt. The default value is 80.
Example: TxMaxCoalescedFrames=80;
• RxCoalescingTicksDuringInt. Configures the number of Rx Host Coalescing Ticks in microseconds
during interrupt. This determines the upper-boundary of the time interval that the device will generate
interrupts if one or more frames are received during interrupt handling. The default value is 75.
Example: RxCoalescingTicksDuringInt=75;
• TxCoalescingTicksDuringInt. Configures the number of Tx Host Coalescing Ticks in microseconds
during interrupt. This determines the upper-boundary of the time interval that the device will generate
interrupts if one or more frames are received during interrupt handling. The default value is 75.
